The codimerization of quadricyclane (QC), the valence isomer of norbornadiene (NBD), with norbornene compounds was studied in the presence of Pd(O) complexes.Codimerization of QC with norbornene, 5-methyl- and 5-methylenenorbornene, exo-tricyclo2,4>octene-6, tetracyclo2,4.03,7>nonene-8, and penta- and hexacyclic NBD dimers was carried out in the presence of PPh3-activated Pd2(DBA)3*CHCl3 to afford a new class of hexa- to nonacyclic strained hydrocarbons with exo- and endo-tetracyclo2,4.03,7>nonane fragments.
